The global economy has become so unbalanced that even government ministers who would normally have trouble explaining supply or demand clearly recognize that something has to give. To a very large extent the distortions are caused by China's long-standing policy of pegging its currency, the yuan, to the U.S. dollar. But as China's economy gains strength, and the American economy weakens, the cost and difficulty of maintaining the peg become ever greater, and eventually outweigh the benefits that the policy supposedly delivers to China. In the first few weeks of 2011 fresh evidence has arisen that shows just how difficult it has become for Beijing.
Twenty years ago, China's leaders decided to ditch the disaster of economic communism in favor of privatized, export-focused, industry. The plan largely worked. Over that time, China has arguably moved more people out of poverty in the shortest amount of time in the history of the planet. But somewhere along the way, China's leaders became addicted to a game plan that outlived its usefulness.
